constructive interference [kən′strək·div ‚in·tər′fir·əns] (physics) Phenomenon in which the phases of waves arriving at a specified point over two or more paths of different lengths are such that the square of the resultant amplitude is greater than the sum of the squares of the component amplitudes.

| Constructive interference creates a moving pulse along the axis of the apparatus whose speed varies according to the configuration of the experiment. Our calculations were based on coming up with the best way of predicting what this constructive interference would be," Hammonds says. If their path difference is exactly the particle's wavelength or an integer multiple of it, the waves are "in phase" and harmoniously merge with each other--an effect known as constructive interference. |
